What types of medication should UAS remote pilots avoid when actively flying?

• A. Medications that improve alertness
• B. Non-prescription vitamins
• C. Any medicines that will affect the remote pilot's mental state
• D. Vaccines

Answer: (C)

The main idea is safety through clear mental and physical capability. When actively piloting a UAS, you must have full alertness, good judgment, and precise motor control. Medications that affect your mental state can dull reaction times, impair decision-making, or cause drowsiness or dizziness. Any medicine that could alter how you think or move can compromise your ability to control the aircraft and respond to hazards, so you should avoid flying while taking such medications or until you know how they affect you.

Vaccines and non-prescription vitamins generally don’t impact immediate flying performance, so they aren’t the same risk. Medications that are intended to boost alertness might still carry side effects that impair performance, which is why the broad rule—avoid any medicines that affect mental state—best addresses safety while you’re in the air. If you’re unsure about a medication’s effect, consult a health professional and refrain from flying until it’s clear you’re unimpaired.
